Abstract
We have used noncontact atomic force microscopy (NC-AFM) and scanning tunneling microscopy (STM) to study the rutile TiO2(011) surface. A series of (2n×1) reconstructions were observed, including two types of (4×1) reconstruction. High resolution NC-AFM and STM images indicate that the (4×1)-α phase has the same structural elements as the more widely reported (2×1) reconstruction. An array of analogous higher order (2n×1) reconstructions were also observed where n = 3-5. On the other hand, the (4×1)-β reconstruction seems to be a unique structure without higher order analogues. A model is proposed for this structure that is also based on the (2×1) reconstruction but with additional microfacets of {111} character.
